An update to the Lexicon class is available

This is just to say that the Lexicon class which was introduced in my article entitled 'A Dictionary class which permits duplicate keys' ( has been updated in my follow-up article (

Anyone who downloaded the previous version is requested to download the current version which contains some additional methods and deals with empty value lists in a more robust manner.

If you are not interested in the sorted versions of the Lexicon class, then the download which accompanies this blog contains only the Lexicon class and the ILexicon interface, together with the original example which produces exactly the same output as it did before.

Thanks for reading this and apologies for any inconvenience if you are already using the class in one of your projects.
